Too big for a setup like that. Go 1 step smaller

IMO the MPG with that setup will be in the single digits... Might want to add a huge tranny cooler to your list...

. . . and a 14 bolt sf to the list as well. The 10 bolt will not last with the power and the tires combined. The tires alone are pushing the 10 bolt well past its limits in a heavy avalanche. I'm thinking that a huge tranny cooler might be a mute point too. Don't get me wrong it will help but I see a fully built 60 or a 80 in the near future. Especially when you start spraying. Those 37's create a lot of rolling mass. The 4.88's help but thats still a lot of weight at each end to get rolling and to try and stop all the time.

Could be a mute point...but it's more likely to be a moot point. Know what I mean?
